Fig. 1: CH4 oxidation and CO2 reduction in microcosms, promoted by iron minerals.
From: Electrochemically coupled CH4 and CO2 consumption driven by microbial processes
a CH4 oxidation and CO2 reduction with and without iron minerals in microcosm incubations. The killed control represents the incubation with sterilized soil. Data generated from n = 3 biologically independent samples for each group and error bars indicate standard deviation of the mean. b Proposed mechanism for iron minerals serving as a geo-battery to couple CH4 oxidation and CO2 reduction.
